Man the DX Roc is so sweet, but it breaks in so quickly! Haven't played that many rounds with mine and it's already not as reliably overstable as it was out of the box. I realize that's the point of cycling, but I don't like the idea of so much plastic waste and having to put a fresh one in so frequently.
The new C-line MD3 is the only thing I have found that is a remotely suitable replacement in premium plastic. Definitely a faster disc and maybe not as much glide, but I can pull off exactly the same shots with it. Other stuff I've tried is champ Roc3 and Z Wasp, both were too beefy.
